PENTSTEMON baccharifolius; caule erecto tereti pubescenti-glanduloso, foliis gla- 
berrimis atro-viridibus coriaceis grosse spinuloso-serratis inferioribus spa- 
thulatis intermediis oblongis summis rotundatis, panicula terminali elongata,

At Tab. 4601 we had the pleasure of figuring a handsome 
new Pentstemon, P. Wrightii, reared from Texian seeds gathered 
by Dr. Wright; and now we have the satisfaction of giving 
another equally new and showy species derived from the same 
source, and, like that, quite hardy, flowering through the summer 
and autumn. It is so distinct that we cannot point to any other 
species with which it is at all likely to be confounded. 
Dzscr. Annual? Stems erect, or decumbent at the base, a 
foot to a foot and a half high. Stem scarcely branched (except 
where it terminates in the panicle), terete, stout, and rigid, of a 
purple-brown colour, and, as are the pedicels, bracts, and flowers, 
even the corolla within and without, clothed with minute glandular 
pubescence. Leaves in rather distant pairs, rigid, dark green, 
spreading, coarsely and spinescently toothed or serrated (generally 
less so at the base), glabrous: the lower ones spathulate, up- 
wards on the stem becoming oblong, and finally, nearest the 
flowers, rotundate, obscurely penninerved, all of them quite 
sessile. Panicle terminal, elongated ; primary peduncles opposite, 
three-flowered, bracteated at the setting on of the peduncles and 
pedicels ; dracteas small, broadly ovate, reflexed. Calya small, 
cup-shaped, deeply cut into five imbricating, ovate segments. 
Corolla rich scarlet, an inch and a half long: ¢ube infundibuli- 
form, labially compressed, slightly ventricose below, the mouth
